Specification of Letters Patent.

Patented Aug. 21, 1906.

To all whom it nut conccrn- Beit known that I, VALERIUS D. ANDER- SON, a citizen of-the United States, residin at Clevelanrhin the county of Cuyahoga an State of Ohio, have invented certain new and useful Improvements in Presses, of which the following is specification.

My present invention pertains to improvements in presses, the construction and advantages of which will be hereinafter set forth, reference being had to the annexed drawings, wherein Figure 1 is a side elevation of the press; Fig. 2, a sectional view, on an enlarged scale, taken on the line 1. 1 of Fig. 1 Fig. 3, a top plan View of the'press; Fig. 4, a longitudinal sectional view of the same; Fig. 5, a side elevation of the compressing mechanism; Fig. 6, a sectional view on the line 2 2, Fig. 3; Fig. 7, a similar view on the line 3 3, Fig. 3; Fig. 8, a perspective view of a number of the bars employed to form the body or shell of the press; Fig. 9, an end View thereof; Fig. 10, a view illustrating a modification of the form of bars employed; Fig. 11,'a side elevation of a portion of a press, showing a modification of the means employed for adjusting the discharge-plug or disintegrating member; and Fig. 12, a vertical sectional view thereof.

This invention. is in a sense an improvement over the presses shown and claimed. in myformer patents, Nos. 731,734 and 731,737, dated June 23, 1903, to which reference is hereby made. 1

The main objects of the present invention are, first, to provide means for preventing rotation of the stock within the press as it is forced longitudinally therethrough; second, to provide a simple means for eflecting the adjustment of the disintegrating-head or discharge-plug, and, lastly, to so construct the member which carries the final compression screw or screws that, acting with the screw in the feed end'of the press, it shall partially extract or force out a portion of the oil from the stock previous to its being given the final compression. The construction by which treat cotton-seed meal from which the hulls.

of the seed have been removed and other members G and M is a rod or shaft P, upon materials of a similar nature. Where the hulls are absent from the material, it is of too soft a consistency to be satisfactorily treated portion of the shaft C,

. shaft at all times.

in the presses hereinbefore referred to.

Other advantages of the present construction will appear from the following description.

In the drawings, A B denote suitable standards in which are journaled the ends of a shaft C, said shaft, aswill be seen upon reference to'Fig. 4, being cylindrical at the head or feed end of the press and polygonal throughout the remaining portion thereof. Surrounding the cylindrical section of the shaft is a quill D, provided with a series of separate and distinct screws E F, any num: ber being permissible in use. The outer ene of the quill extends through a standard or frame G and has mounted upon it a gear H,-

similar gear I being carried by the shaft C. Continuous motion is imparted to gear I, and consequently to the shaft, While gear H and the attached quill will rotate until a certain pressure is obtained-in that portion of the press, when they will come to rest and rema n in that condition until the pressure again falls below a predetermined point- This feature forms the subject -matter of the aforesaid applications.

A sleeve J is mounted on the polygonal the interior formation of the sleeve corresponding to the contour of said shaft, so that the sleeve rotates with the The sleeve is held to its position with reference to the quill by a follower-nut K. As will be seen upon reference to Figs. 4 and 5, the innermost portion of the sleeve, or that immediately adjacent to the quill, is made tapering, the end being of the same diameter as the quill and gradually increasing to the full diameter, which is materially larger than that of the quill.

A screw L is formed upon thesleeve J and serves to force the material under treatment through an opening formed in the standard or frame M and over the tapering disintegrating member or head N. As will be seen,

thestandardor frame M is made stationary and the opening therein is enlarged in line "with the dlsc'harge. The disintegrating memwhich are hingeda series of ribs Q, one set thereof being arranged above and the other below said rod. Each rib is provided with a ICC series of laterally-extending lugs R, to which are secured by the use of tap-screws or the like relatively heavy bars S, the bars being of. such length as to fill the space between the members G and M or the member M and the feed-hopper T, secured to the standard G. A series of smaller bars U is mounted intermediate the bars S, half ring-sections V being bolted to the ends of bars'U and also, by-preference, at a point intermediate said ends. The bars S are also secured to the rin.g-sections. To properly space the bars, strips or thin steel plates W are riveted to the opposite faces of each alternate bar or to one side of each, asdesired. Some of the bars U are provided with longitudinally-extending grooves or channels X upon their inner faces, as will be seen upon reference to Figs. 6 to 9, inclusive.

The reverse of this construction is shown in Fig. 10, wherein the face of each .bar is formed with a projecting rib Y. With either construction groovesv or channels will be formed upon the interior face of the shell or barrel, which will effectually prevent rotation of the stock as it passes through the press, but still permit it to be forced lengthwise of the barrel by the screws. Each of the ribs Q .is extended outwardly at its free end, as at Q, and bars A are held in contact with said members by bolts B, thus securely holding the two sections of the shell or .barrel together. Lugs C C also extend laterally from the frame members or standards G and M, being engaged by the locking-bars when the press is closed. These lugs serve to prevent the shell from being twisted and assist in rendering the whole structure rigid throughout.

The operation of the press thus far described is as follows: The material from which the oil is to be eXt-ractedsuch, for instance, as cotton-seed mealis introduced into the feed-hopper, motion having been imparted to the quill and the sleeve. The material is given an initial compression in the forward portion of the barrel or shell of the press by the motion of the screws E F, the screweE serving to force it toward the screw F and the material intermediate the screws moving longitudinally in the shell or barrel, but not rotating therein. The ribs or depressions formed in the interior face of the barrel or shell and 'hereinbefore referred to prevent the rotation of the material in the space intermediate the screws, and conse-' quently it is compacted at this point; Screw F gradually withdraws the compacted material from the space and feeds it forward in the press over the inclined end of the sleeve J, which of course puts it under a higher compression than was obtained in the forward portion of the press. It is from this point on toward the discharge end of the press that the greatest compression takes place, and it will be readily seen that forcing the material from the screw F up over the inclined face of the sleeve J will compress the mass to a great extent. Where hulls are present in the material being treated, it is not necessary to employ this inclined face; but where hulls are absent, as in cottonseed meal, it becomes essential to first extract part of the oil before giving the final pressure to the material.

Otherwise the oil will not separate freely,

and a great deal of the. solids will be forced out through the slots between the bars. The present construction, however, obviates this difliculty, and the smaller screw or worm upon the. sleeve effects the final compression of the material and forces it outwardly through the discharge-ope:ring in the standard M and over the disintegrating member N. As hereinbefore stated, the sleeve with its screw rotates constantly, whereas the quill and its screws or worms rotate until a certain pressure obtains in that portion of the press where the sleeve works, when they will come to a state of rest and remain in such position until the screw L relieves the pressure sutliciently to enable the friction-clutch or other means employed for driving the quill to again rotate the same. It is to be observed that the channels or ribs formed in the interior of the barrel extend throughout the ength thereof, so that the material, which is put under great pressure, does not rotate at any point between the screws or worms.

While cotton-seed meal has been referred to specifically, it will be understood that the press is adapted to the treatment of any material from which it is desired to extract the oil. The apparatus shown enables me to express oilfrom substances which have heretofore not been economically treated, for the reason that no process or means for handling the same was known by which the oil could be successfully extracted.

The construction shown in Figs. 11 and 12 yet remains to be described. Instead of threading the disintegrating head or plug internally the hub a of the head I) is provided with a polygonal opening of a shape to fit upon the corresponding portion of the main shaft C and to rotate therewith. The threaded sections of the shaft do not,-how ever, make contact with the head. Hence the latter may be moved lengthwise of the v shaft to adjust or carry its forward tapered end more or less into the inclined dischargeopening formed in the standard M of the press, as heretofore described. Mount-ed upon the threaded end of the main shaft 0 in rear of the head or plug?) is ,a gear-wheel d, the hub of 'which bears directly against the rear face or hub of the plug. A second shaft e is mounted in the frame of the press, said shaft carrying a pinion f, which is splined thereto, so. that it rotates with the same, the pinion, -however,'being free to move lengthwlse on the shaft by reason of the ke'yway g' tighten up the discharge plu or head, a handle h is slipped on the end the small shaft I c, and by holding said handle stationary while the shaft 0 is revolving said lastnamed shaft will screw into the ear, thereby causing it to advance along the s aft and consequently force the plug in'toward the barrel of the press. The shrouding of the pinion causes it to move along its shaft as the gear is adjusted along shaft C, the two bein thus alwa s held in mesh with each other. en it is esired to slacken up the discharge-plu the handle is turned in the direction in whidli the small shaft e revolves, although somewhat faster than said shaft, and this carries the spur gear and pinion toward the rear end of the press, thepressure of the stock issuing from the press forcing the plug back along the shaft and maintaining contact between the hub of the gear and said plug. The shafts of the press revolve slowly while it is in operation, which permits the steps just mentioned to be carried out. The pinion, shaft e, and the spur-gear revolve at all times when the press is in operation, exceptwhen the shaft 6', and consequently pinion f, and the gear are being held against rotation in the act of advancing the head or lug. It is of course manifest that this particular adjustin mechanism may be employed with an orm of -press of the same general type as t at herein Q" 1 shown is not essential to the successful 0 described.
